SWlTCH-STAND F OR RAILWAYS.

' SPECIFICATION forming part of Letters Patent No. 277,539, dated May15, 1883.

' Application filed January 31, 1883. (No model.)

switch-stands, whereby we simplify their construction, and thereforeincrease thefacility for manipulation and the safety of passing trains,and whereby we also economize room when it is needed in a directionperpendicular to the main track. WVe attain these objects by themechanism illustrated in the accompanying drawings, in which- Figure 1is an elevation of our stand in working position, looking in a lineparallel to main track. Fig. 2 is a plan of stand, showing itsconnection with the switch-rail. Fig. 3 is a vertical section of stand.Fig. 4 is a section on the line X of Fig. 3. a Fig. 5 is an isometricview of our locking device. Figs. 6 and 7 illustrate different positionsof the top of stand,

the lines a (1 being perpendicular to the line of the main track.

The same letter refers to the same part throughout. The points which arepeculiar to our switch are set forth in the following de-. scription.

Those portions of the stand represented by the letters H E M S are inone casting, constituting the stand proper. The shaft B (3 correspondslZOythG shaft in ordinary revolvin g switch-stands, its axis being thecenter of revolution. Its weight rests upon the top H of the stand E,and it is held in position by thejournalI-box L, which surrounds it, andby the cylindrical recess in the casting M, in which the lower end, 0,of the shaft rotates. The horizontal shank D of the shaft is bent to avertical direction at G, and provided with an upset head, 0. To thevertical portion G, and resting upon the head 0, is attached theconnecting-rod I, through which the motion is imparted to theswitch-rail. The breadth of the slot R of the c onnecting-rod P is lessthan the diameter ofthe depending portion G, about which it turns, butis greater than the breadth of the horizontal shank D, and is alsogreater than the breadth of the lug S of the casting M of the stand. Thesize of the casting M is such that the rim T of the connecting-rod P inall its working positions projects under it, preventing the removal ofthe connecting-rod in a vertical direction, while the track-man, toeffectits removal, having disconnected it from the switch-rail by firstremoving the bridlebar from the rails in thevusnal manner and allowingit to fall .till it disconnects from the 'rod, has only to turn itthrough one hundred and eighty degrees in a horizontal plane till theslot R comes under the lug S, when, by lifting, the rod readily passesthe lug S and the horizontal shank D and is free. This combination doesaway with the nuts, bolts, split keys, and thread, which, in common useat the lower end of the shaft, are often accidentally or maliciouslymisplaced or disconnected, and affords a safe .and simple means ofrapidly connecting or disconnecting the rod with the revolvingshaft.

The thickness of the casting M being greater than its distance above therim T of-the connecting-rod P, the bottom 0 of the shaft cannot beremoved from its recess in the casting M when the connecting-rod P is inany of its working positions. This, in combination with the fact thatthe lock and its co-operating parts, as in ordinary revolving stands,hold the shaft against any horizontal motion when locked, makes theshaft unremovable in any direction when the stand is locked, even thoughthe journal-box L be maliciously removed.

Our manipulating-lever J N is jointed on the rivet V, the hand-section Nfalling into the recess (g, formed in the stand, and correspondiug to arequired position of the switch-rail whenever that position is reached,automatically carrying the perforated end of the lug Z through therecess W, and in front of the shoulder-section A, to receive the hasp ofthe lock.

When it is required to economize room in a direction perpendicular tothe main track, the top or table of the stand is constructed so that thecenter position of the lever is toward the main track and the other twopositions parallel with main track, (see Fig. 7 the lever, whenhorizontal, being at right angles to the shank D, the room usually takenup by the lever when on the side of the stand opposite main track beingsaved.

In Fig. 6, a, c, and d are the three positions of the depending portionG of the crank, the

semicircle cf being the top of the stand, all as shown in position in Fi2. With this construction the lever projects, in its differentpositions, in the directions Bf, B h, and B e, the projection of thelever away from main track in the direction B f often using space neededfor other tracks.

I In Fig. 7, a c d shows, as before, the three positions of thedepending portion G of the crank, the corresponding positions of thelever being, as before, Bf, B h, and B. c, the top of stand H H in Fig.2 being turned ninety degrees in a horizontal plane, as in Fig. 7, andthe lever being placed upon the shaft at right angles to the shank D. Bythis change inthe top or table of the stand the lever never projects inthe direction B a, and the room taken 1. In aswitch-stand,thecomhination of theprojecting casting M, having lug S,with the rim '1 of the connecting-rod P, shaft B (J, crank D G,and upsethead 0, all made substantially as specified, for the purposes set forth.

2. In a double-throw switch, the combination, with the lever N J,arranged upon the shaft B at a right angle to the crank D G, of thestand, constructed substantially as described, and havingthe top H, withits recesses, arrangedin aposition quartering to correspond with theposition of said lever on the shaft,as set forth.
